How to Delete an Image from Folder in CodeIgniter After Database Deletion

If you're developing a web application using CodeIgniter, you may encounter a situation where you need to delete not just the database record of an image, but also the actual image file residing in a folder on your server. This process is essential to free up disk space and maintain an organized file directory. In this guide, we will delve into how to accomplish this task step-by-step.

The Problem

When you delete an image from your gallery, you might notice that only the record in the database gets deleted while the image file remains in the folder. To achieve proper deletion of both the database record and the image file, we must modify our current implementation.

Current Setup

Our current setup includes a model, a controller, and a view. Below is a quick overview of each component:

Model: Manages database operations, particularly the delete operation.

Controller: Handles the logic for deleting an image and fetching updated records from the database.

View: Displays the gallery with images and provides delete actions.

Current Model Code

Here’s the current method for deleting a record using the model:

Current Controller Code

This is how the controller manages the deletion process:

The Solution

To ensure that the image file is deleted from the server as well, we'll enhance the delete_image method within the controller. Below are the step-by-step changes we need to make:

Step 1: Retrieve the Image Path

Before deleting the image record, retrieve the file path of the image that you wish to delete. You need to ensure that you have access to this information in your current setup.

Step 2: Check If the File Exists and Delete It

We'll use the unlink() function in PHP to delete the image file. Here’s the modified code for the delete_image method:

Step 3: Load Updated Records

After successfully removing the image from the folder and the database, the updated list of records is fetched and sent back to the view to display the current state of the gallery.

Conclusion

Following these steps will not only help you remove images from the database but also keep your server clean by ensuring that image files are deleted from your folders. Always remember to check if the file exists before trying to delete it to avoid potential errors in your application. By implementing this method, you can enhance the management of images in your CodeIgniter application effectively.
